The flow of natural gas in gas pipelines has been attended with the problem of pressure drop
along the pipeline. The magnitude of the pressure drop is known to be affected by certain flow variables such as
flow velocity or volumetric flow rate, bulk flow temperature, ambient conditions, nominal pipe diameter, pipe
roughness (relative or absolute), etc. Other factors that will affect throughput and pressure drop relationship are
design and construction of the piping system, piping materials, pipe wall thickness, terrain of a place,
enlargement and contraction along the pipes, pipe conditions (vacuum and weight of the overlying materials be
it water or earth mass), etc. It is well established that the flow of natural gas in gas pipelines is not essentially
single phase flow situation...............

Pipelines Network System

Abstract

Mathematical models have been developed to ascertain the exact position of commencement of
dew point in gas pipelines network system transmitting gaseous components or complex hydrocarbon mixtures.
Attainment of dew point in gas transmission pipelines leads to flow separation. Inadvertently, two-phase flow
situation will result with liquid and gas holdups coexisting. The liquid holdup eventually settles at low points in
the pipe as condensates. The condensate so formed obstructs flow leading to increased pressure drop along the
line. The driving force of a flowing fluid stream is a function of the overall line pressure drop and line
throughput. The higher the two militating factor, the higher the pumping and compression power. It is very
worthy to note the exact point on a gas pipeline at which condensation will set in; drain plugs could be installed
at such points for periodical removal of the condensate so formed. This will offset the high cost of investment
on gas pipelines assets facilities.

The main objective of a successful drilling operation lies in the construction of safe and
economically efficient wells, success of which depends on hitting the target (pay) zone. Although, drilling
oil/gas well is a very complex operation yet a good, efficient and safe drilling operation depends on a good well
plan.
Well trajectory planning requires a mixture of different parameter of interest; the offset data, the contour
mapping, computer technical know-how, core data, safety report, etc., but in the end, it drip down to optimum
identification of the well path, which is a function of exact mathematical model used to precisely calculate the
wellbore trajectory............

Full Article

Vibration generated due to road bumps has a significant effect on the behavior of nearby
buildings;this must be taken into account during design. This paper includes the study of the behavior of
buildings through the stresses in it. Therefore, two types of buildings were used, one structural building and the
other is brick building (nonstructural) and these buildings are two types one and two floors. The soil was taken
sand and clay soil to indicate the type of soil suitable for that absorption of vibrations. ANSYS program is used
to analyze the problem and study some variables affected on the behavior of buildings, such as the speed and
mass of vehicles, the type of road bumps ( plastic, Asphalt and concrete), the width of the road bump and the
distance between the building and road bumps............

This document gives The cost generated per unit in a thermal power station is dependent on
fixed cost and variable cost. The duty of an electrical engineer is to generate power without outage of power
keeping the cost of power generated per unit as low as possible. An engineer can able to reduce the cost of
generated power only when he knows on what factors the cost of generated power depends. Hence he must
know on what factors the fixed cost and variable cost may depend. The Central Electricity Regulatory
Commission (CERC) has the power of deciding the tariff for electricity generated by various power stations.
Tariff is calculated on the basis of fixed cost and variable cost. The power plants have fixed and variable costs.
The fixed cost dependent on return on equity, interest on capital loan, depreciation, interest on working capital,

A composite is a structural material which consists of two or more constituents combined at a
macroscopic level. The constituents of a composite material are a continuous phase called matrix and a
discontinuous phase called reinforcement. Matrix gives shape and protects the reinforcement from the
environment. It also makes the individual fibres of the reinforcement act together and provides transverse shear
strength and stiffness to the laminated composites. The present work deals, epoxy based composite filled with
ultra-light micro-silica is prepared by traditional hand layup method, using ceramic fibre as reinforcement. The
effect of various percentages of micro-silica is investigated on the tensile strength, compression strength, impact
resistance and thermal stability of the composite using Thermo-Gravimetric Analysis(TGA) analysis. The result
reveals that, up to 15% addition of micro-silica enhanced the mechanical properties, thermal stability and
increase the weight. However, the addition of micro-silica beyond 15% decreases the enhanced properties of the
composites.

All most all the Vehicles use Crude Oil extracts as their fuel, the consumption of the fuel is
increasing greatly with the increase in number of Vehicles on road. However , the Crude Oil reserves in the
Earth crust is not going to improve .So there is a need for an alternative fuel which could meet the demands of
the future and this alternative fuel must not be a derivative of Crude Oil. Many fuels were tested on the Internal
Combustion Engines, Acetylene is one of the tested fuels. The present paper involves the use of Acetylene as a
primary fuel and Alcohol as a Secondary fuel in order to avoid the knocking phenomenon in an internal
combustion engine. Using Acetylene as a fuel had its own crests and troughs, the paper investigates working of
SI engine on acetylene with minor changes being done to the Carburetor. Thus reducing the limitations of using
acetylene as a fuel, this makes it fit for use on economic and environment standard. It is more powerful and ecofriendly
alternative fuel option.

Concept of Computer Security

Abstract

Full Article

After many years of work on computer security, computers are not secure till now. The main
reason is that security is expensive to set up and a nuisance to run, so people judge from experience how little of
it they can get away with. Since there's been little damage, people decide that they don't need much security. In
addition, setting it up is so complicated that it's hardly ever done right. While we await a catastrophe, simpler
setup is the most important step toward better security. In a distributed system with no central management like
the Internet, security requires a clear story about who is trusted for each step in establishing it, and why. The
basic tool for telling this story is the ―speaks for‖ relation between principals that describes how authority is
delegated, that is, who trusts whom. The idea is simple, and it explains what's going on in any system I know.
The many different ways of encoding this relation often make it hard to see the underlying order.

Cost-effective operation of wastewater treatment plant is a basic need in engineering, but time to
time it requires optimisations and re-visiting process parameters since the operational environment constantly
changes. Alternation of load, extraneous wastewater sources from industry may lead to instabilities in operation,
which could be managed only with full understanding of the actual environment. Process simulation is a helpful
tool to predict the effect of future operational mode or reactor setup saving energy and cost. In this study the
operation performance of a 2 MLD wastewater treatment plant in Hungary was analysed with the tool of process
simulations. First the model was calibrated applying the actual operation and reactor setup, then new alternatives
were tested and the model results were compared. As a result of the calculations, in addition to the effluent
quality improvement the sludge production could be improved by approximately 20% and the aeration need
decreased by 30%.

This paper focus on modelling and simulation of single phase inverter. An inverter is a circuit
that converts DC sources to AC sources. The model is implemented using MATLAB/Simulink software with
the SimPower System Block Set based on computer simulation. In order to find the harmonics content and total
harmonic distortion (THD), Fast Fourier Transform (FFT) analysis is used using MATLAB Simulink software.
It is shown that the performance of the inverter circuit with the harmonics filtering circuit having a THD value
of 28.79% is better than the inverter circuit without the harmonics filtering circuit having a THD value of
87.53%.
